All times for min, max, average and median are in microseconds, and length is in bytes. Benchmarks results include writing, reading, and pruning of 3GiB (3 * 1024 * 1024 * 1024) of data on both HDD and SSD with a block size distribution from mainnet. See the PR at bcoin-org/bcoin#703 for further details.
